What resources does Steel Puppeteer expose?

The server provides access to browser console logs (`console://logs`) and captured screenshots (`screenshot:// `).

What credentials does it need?

It reads `STEEL_LOCAL`, `STEEL_API_KEY`, `STEEL_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
